Changing State of Matter: Does it Affect Mass of Chocolate Easter Eggs?

This experiment investigates whether changing the state of matter of chocolate Easter eggs from solid to liquid changes their mass. Three trials were conducted, and the results showed that the mass of the eggs remained the same after melting. The hypothesis that melting the eggs would change their mass was proven incorrect. The experiment used Reeses's Chocolate eggs and a microwave to melt them.

  1. Easter chocolate eggs are gooood …no matter how

  2. Hypothesis Hypothesis 1 Hypothesis 2

  3. Does changing the state of matter change the mass of the object? Problem We want to know if the mass of ten chocolate Easter eggs will change after melting them.

  4. Hypothesis 5 Students 19 Students • If we take the same amount of chocolate Easter eggs, take their mass and melt them, we think that melting them will change their mass. • If we take the same amount of chocolate Easter eggs, take their mass and melt them, we think that melting them will NOT change their mass.

  5. Materials • One bag of Resse’s Chocolate eggs. • A scale • A cup • Microwave to melt the chocolate Easter eggs.

  6. Procedure • Measure the mass of ten unwrapped chocolate Easter eggs in the cup on the scale and record. • Melt the chocolate Easter eggs in the cup in the microwave for one minute. • Measure the mass of the melted chocolate Easter eggs with the cup. • Conduct multiple trials (3).

  7. Procedure

  8. Variable Independent Variable: We changed the state of matter of the chocolate Easter eggs from solid to liquid by adding heat. Dependent Variable: The mass of the chocolate Easter eggs.

  9. Control Everything else stayed the same: same type and amount of chocolate Easter eggs. We used ten to conduct each of the three trials. We used the same procedure each time.

  10. Results Students collected the information and wrote it in their Science journals.

  11. Results

  12. Results We conducted 3 trials and measured the mass before and after melting the Easter eggs.

  13. Conclusion We learned that changing the state of matter of the Easter chocolate eggs from solid to liquid did not change the mass of the ten eggs. The hypothesis 2 was correct while hypothesis 1 was incorrect. After the second trial, the students from hypothesis 1 started to change their prediction based on the data. We learned that matter can change its form due to changes in temperature while its mass remain the same.
